Update 3:18 p.m., Dec. 6: The National Weather Service this afternoon issued flash flood warnings for the following waterways in Travis and Williamson counties:

  • South Fork San Gabriel River

  • Onion Creek At US 183 affecting Travis County

Update 10:47 a.m., Dec. 6: The National Weather Service this morning issued a flash flood watch for Travis, Williamson and Hays counties.

According to the National Weather Service, 3-5 inches of rain are expected across the eastern Hill Country and along the I-35 corridor and 4-6 inches of rain are expected east of I-35.

Rainfall should end Friday night and clear up by Saturday morning, per the flash flood watch.

Correction: This article originally stated the National Weather Service issued a flash flood warning, which was incorrect. The National Weather Service has issued a flash flood watch for parts of Travis, Williamson and Hays counties.

A flash flood warning has been issued for the South Fork San Gabriel River.

Original post: With at least 1-2 inches of rainfall and possible flooding predicted for Friday, Lower Colorado River Authority officials have not ruled out preventive activity for the Highland Lakes chain.

This includes Lake Travis, which remains at 100 percent capacity following heavy October rains that caused several pockets of flooding throughout the Central Texas region.

“LCRA is closely monitoring inflows to the Highland Lakes and will be ready to react as needed,” LCRA Public Information Officer Clara Tuma said. “At this point it is too early to tell whether we will need to open any floodgates, but with heavy rain in the forecast and full lakes, it is certainly a possibility.”

LCRA officials are encouraging residents living along the lakes to sign up for LCRA’s Flood Operations Notification Service, or FONS, to be alerted if flood operations need to be initiated at dams along the Highland lakes, and to monitor the LCRA Hydromet for current rainfall totals, streamflow and lake levels.
